帧动画

1.anim中的动画布局，加上许多具有连续性的图片

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="false">    <item android:drawable="@drawable/a1" android:duration="400" />    <item android:drawable="@drawable/a2" android:duration="400" />    <item android:drawable="@drawable/a3" android:duration="400" />    <item android:drawable="@drawable/a4" android:duration="400" />    <item android:drawable="@drawable/a5" android:duration="400" />    <item android:drawable="@drawable/a6" android:duration="400" />    <item android:drawable="@drawable/a7" android:duration="400" />    <item android:drawable="@drawable/a8" android:duration="400" />    <item android:drawable="@drawable/a9" android:duration="400" /></animation-list><span style="font-size:18px;"></span><pre name="code" class="html">android:oneshot="false"

指明动画是否重复

2.activity_main.xml布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.rj141.sb.lianxuanimation.MainActivity">    <ImageView        android:id="@+id/img"        android:layout_width="wrap_content"        android:layout_height="0dp"        android:layout_weight="8"        android:scaleType="center"        android:src="@drawable/drawable_rotate"        android:contentDescription="@string/app_name"        android:layout_gravity="center_horizontal" />    <Button        android:id="@+id/start"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"        android:text="@string/start"        />    <Button        android:id="@+id/stop"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"        android:text="@string/stop"        /></LinearLayout>

3.MainActivity.java文件

public class MainActivity extends ActionBarActivity implements View.OnClickListener{    private Button start,stop;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        start=(Button)this.findViewById(R.id.start);        start.setOnClickListener(this);        stop=(Button)this.findViewById(R.id.stop);        stop.setOnClickListener(this);    }    public void onClick(View v){        int id=v.getId();        if(id==R.id.start){            ImageView iv=(ImageView)this.findViewById(R.id.img);            AnimationDrawable ad=(AnimationDrawable)iv.getDrawable();            ad.start();        }        else{            ImageView iv=(ImageView)this.findViewById(R.id.img);            AnimationDrawable ad=(AnimationDrawable)iv.getDrawable();            ad.stop();        }    }}
